[amsat-bb] Re: ANDE-2 Deployment

[Ivan Galysh]

The satellite is made mostly of parts from Digikey.
The following processors are flying:

Pollux: 1 - Atmega168, 3 - Atmega168
Castor: 1 - LPC2106, 2 - Atmega168, IGLOO FPGA AGL125, Atmega128
Printed circuit boards from www.pcbexpress.com

When I get a chance, I'll see how much info I can release about the 
design and components. They are all commercial parts.
Sensors are gyroscopes from Melexis and Analog Devices. Magnetometer is 
the PNI Micro mag 3-axis unit.

I'm preparing for PDR in a few weeks on another satellite program. Once 
I get past it, I'll put out more info on the sensors and telemetry.

I also want to write an article on the electronics.

Oh, and the radio transmitter in the satellites are based on this module.
